How to become a project management consultant. So I wanna first start with clarifying what a consultant is. It’s a person who provides expert advice professionally. Well, consultants can be within a corporation. They can be a corporate employee, or they can be an external contractor. And if they’re an external contractor, they can work for someone else’s firm or your own firm. So it’s very important to have knowledge and skills in business, really understanding and having clarity on your service offering.
